Reptiles A. Cladistics 1. Many Groups of Organisms
Reptiles A. Cladistics 1. Many groups of organisms are “polyphyletic” a. This means that the group combines 2 or more lineages - example=fish 2. Cladistics follows only pure lineages going back in time - example Osteichthys B. Reptile Classifiecation - looks like a polyphyletic group 1. Dry skin - no loss of water through skin like amphibians 2. Aminotic egg - an egg that can survive on dry land - in contrast with the amphibian egg C. Mammals and Birds are derived from different lineages of reptiles (We will see below) D. Stem Reptiles 1. Different lineages based on the temporal region of their skulls - number of holes (or bars) a. These holes are necessary to accommodate large jaw muscles b. Anapsid Skull - no holes in temporal - jaws can move fast, but with little force 1. Muscles that move the jaw are small 2. There is no good paleotological evidence for the transition between amphibians and reptiles - no fossil intermediates a. Fossil amphibians have lots of dermal bones in skull b. Amphibians have no temporal openings in skull 1. (Aside) both fossil amphibians and primitive reptiles have a parietal “eye” that senses light and dark (“third” eye in middle of head) c. Reptile skull is higher than amphibian to accomodate larger jaw muscles d. Of the modern reptiles only turtles are anapsids 2. Diapsid Skull - has holes in the temporal region a. Diapsid reptiles gave rise to lizards and snakes - they have a diapsid skull 1. Also Tuatara, crocodiles, dinosaurs and pterydactyls Reptiles b. One group of diapsids also had a pre-orbital hole in the skull in front of eye - this hole is still preserved in the birds - this anatomy suggests strongly that the birds are derived from the diapsid reptiles 3. -
Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha)
Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) by Richard Kissel A thesis submitted in conformity with the requirements for the degree of doctor of philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto © Copyright by Richard Kissel 2010 Morphology, Phylogeny, and Evolution of Diadectidae (Cotylosauria: Diadectomorpha) Richard Kissel Doctor of Philosophy Graduate Department of Ecology & Evolutionary Biology University of Toronto 2010 Abstract Based on dental, cranial, and postcranial anatomy, members of the Permo-Carboniferous clade Diadectidae are generally regarded as the earliest tetrapods capable of processing high-fiber plant material; presented here is a review of diadectid morphology, phylogeny, taxonomy, and paleozoogeography. Phylogenetic analyses support the monophyly of Diadectidae within Diadectomorpha, the sister-group to Amniota, with Limnoscelis as the sister-taxon to Tseajaia + Diadectidae. Analysis of diadectid interrelationships of all known taxa for which adequate specimens and information are known—the first of its kind conducted—positions Ambedus pusillus as the sister-taxon to all other forms, with Diadectes sanmiguelensis, Orobates pabsti, Desmatodon hesperis, Diadectes absitus, and (Diadectes sideropelicus + Diadectes tenuitectes + Diasparactus zenos) representing progressively more derived taxa in a series of nested clades. In light of these results, it is recommended herein that the species Diadectes sanmiguelensis be referred to the new genus -

Meet the Herps!
Science Standards Correlation SC06-S2C2-03, SC04-S4C1-04, SC05-S4C1-01, SC04-S4C1-06, SC07-S4C3-02, SC08- S4C4-01, 02&06 MEET THE HERPS! Some can go without a meal for more than a year. Others can live for a century, but not really reach a ripe old age for another couple of decades. One species is able to squirt blood from its eyes. What kinds of animals are these? They’re herps – the collective name given to reptiles and amphibians. What Is Herpetology? The word “herp” comes from the word “herpeton,” the Greek word for “crawling things.” Herpetology is the branch of science focusing on reptiles and amphibians. The reptiles are divided into four major groups: lizards, snakes, turtles, and crocodilians. Three major groups – frogs (including toads), salamanders and caecilians – make up the amphibians. A herpetologist studies animals from all seven of these groups. Even though reptiles and amphibians are grouped together for study, they are two very different kinds of animals. They are related in the sense that early reptiles evolved from amphibians – just as birds, and later mammals, evolved from reptiles. But reptiles and amphibians are each in a scientific class of their own, just as mammals are in their own separate class. One of the reasons reptiles and amphibians are lumped together under the heading of “herps” is that, at one time, naturalists thought the two kinds of animals were much more closely related than they really are, and the practice of studying them together just persisted through the years. Reptiles vs. Amphibians: How Are They Different? Many of the differences between reptiles and amphibians are internal (inside the body). -
Diversity and Conservation of Amphibians and Reptiles in North Punjab, Pakistan
Diversity and conservation of amphibians and reptiles in North Punjab, Pakistan. MUHAMMAD RAIS, SARA BALOCH, JAVERIA REHMAN, MAQSOOD ANWAR, IFTIKHAR HUSSAIN AND TARIQ MAHMOOD Department of Wildlife Management, PMAS Arid Agriculture University Rawalpindi, Pakistan. Corresponding Author: Muhammad Rais, Visiting Scholar, Department of Biology, Indiana-Purdue University Fort Wayne, Indiana, USA. Email: [email protected] ABSTRACT - Amphibians and reptiles are the most neglected and least studied wildlife groups in Pakistan. The present study was conducted in the selected areas of districts Rawalpindi, Islamabad and Chakwal, North Punjab, Pakistan, to obtain data on herpetofaunal species richness and abundance from February, 2010 to January, 2011 using area-constrained searches. A total of 35 species of amphibians and reptiles (29 genera, 16 families, four orders) were recorded from the study area. Of the recorded species, 30 were reptiles (25 genera, 13 families, three orders) and five were amphibians (four genera, three families and a single order). A total of 388 individuals belonging to 11 recognizable taxonomic units (RTUs) with a population density of 0.22 individuals/ ha. and 4.10 encounters were recorded. Of the recorded RTUs, two (lacertids and skinks) were rated as uncommon, seven (hard-shell turtles, soft-shell turtles, agamids, gekkonids, medium and large-sized lizards, non-venomous snakes and venomous snakes) as frequent and two (toads and frogs) as common. Districts Rawalpindi/ Islamabad had higher species richness while District Chakwal had relatively higher species diversity and evenness. Threatened species of the area included the Narrow-headed Soft-shell Turtle (Chitra indica), Indian Soft-shell Turtle (Nilssonia gangetica), Peacock Soft-shell Turtle (Aspideretes hurum), and Brown River Turtle (Pangshura smithii). -

Through an extensive review of information on Cuban herpetofauna, including protected area management plans, we present the first comprehensive inventory of introduced amphibians and reptiles in the Cuban archipelago. We classify species as Invasive, Established Non-invasive, Not Established, and Transported. We document the arrival of 26 species, five amphibians and 21 reptiles, in more than 35 different introduction events. Of the 26 species, we identify 11 species (42.3%), one amphibian and 10 reptiles, as established, with nine of them being invasive: Lithobates catesbeianus, Caiman crocodilus, Hemidactylus mabouia, H. angulatus, H. frenatus, Gonatodes albogularis, Sphaerodactylus argus, Gymnophthalmus underwoodi, and Indotyphlops braminus. We present the introduced range of each of the 26 species in the Cuban archipelago as well as the other Caribbean islands and document historical records, the population sources, dispersal pathways, introduction events, current status of distribution, and impacts. -
A New Species of the Sauropsid Reptile Nothosaurus from the Lower Muschelkalk of the Western Germanic Basin, Winterswijk, the Netherlands
A new species of the sauropsid reptile Nothosaurus from the Lower Muschelkalk of the western Germanic Basin, Winterswijk, The Netherlands Nicole Klein and Paul C.H. Albers Acta Palaeontologica Polonica 54 (4), 2009: 589-598 doi: http://dx.doi.org/10.4202/app.2008.0083 A nothosaur skull recently discovered from the Lower Muschelkalk (early Anisian) locality of Winterswijk, The Netherlands, represents at only 46 mm in length the smallest nothosaur skull known today. It resembles largely the skull morphology of Nothosaurus marchicus. Differences concern beside the size, the straight rectangular and relative broad parietals, the short posterior extent of the maxilla, the skull proportions, and the overall low number of maxillary teeth. In spite of its small size, the skull can not unequivocally be interpreted as juvenile. It shows fused premaxillae, nasals, frontals, and parietals, a nearly co−ossified jugal, and fully developed braincase elements, such as a basisphenoid and massive epipterygoids. Adding the specimen to an existing phylogenetic analysis shows that it should be assigned to a new species, Nothosaurus winkelhorsti sp. nov., at least until its juvenile status can be unequivocally verified. Nothosaurus winkelhorsti sp. nov. represents, together with Nothosaurus juvenilis, the most basal nothosaur, so far. Key words: Sauropterygia, Nothosaurus, ontogeny, Anisian, The Netherlands.
